For water in glass plastic or styrofoam cups - which will freeze fastest?
Assuming they are the same or similar shape and volume, water in glass would freeze first, then plastic then foam. Foam allows transfer of heat out of water more slowly than plastic and the glass probably has the highest rate of heat radiation of the three.
Which freezes first hot cold or salt water?
My fiance and I did an experiment with hot and cold water to see which one would make ice cubes faster. Honestly they froze at about the same time. He was taught that because its hot the molecules come together faster in the cold air, but during the test it was equal. As for the salt water I would think that would come in last.
Does pure water freeze faster than regular water?
Yes pure (distilled) water will freeze faster than tap water because any impurities lower the freezing point. Regular water has minerals dissolved in it (such as calcium phosphate, and iron) and will freeze at a very slightly lower temperature than completely pure water.
Will water freeze at 32 degrees Celsius?
No. But it would be great for a bath.
Is it true that hot water freezes faster than cold water?
Hot water does not freeze faster than cold water. Nor does cold water boil faster than hot water. For water to freeze, you must remove enough heat to bring its temperature down to 0 C. The colder the water is, the less heat you have to remove before it freezes. I have no idea why this rumor is cirulating the net and the world. It is just totaly insane to even think that that could be true. If you have just heated the water to 100 degrese, then it has that much more to cool down to 0. If the waterisat 30 then it is obvious that the 30 degree would cool faster. Really now. It's not exactly a rumor, it's true...at least sometimes. In scientific communities it's called "The Mpemba Effect" and was named after a Tanzanian student named Erasto Mpemba who first raised the question in the late 60s. When a container of water is placed in a freezer, there are many factors which can affect the length of time it will take to freeze, and under the proper combination of circumstances, a given volume of hot water in a container may freeze faster than the same volume of cold water. So, the best answer is, "Sometimes."
Will water freeze faster in a plastic cup or a metal cup?
Water in a metal cup will freeze faster because metal conducts coldness and energy the most. trust me, I did a project with a metal, plastic, glass, and paper to see which cup would freeze the quickest. Hopefully this answer helped.
Does water freeze faster in plastic or metal?
it would melt faster in a glass container faster.
What would freeze faster 7-up or water?
Water will freeze faster than 7-up. This is due to the extra stuff in 7-up that isn't in water, such as sugars, syrups and caffeine.
What freezes faster in less than an hour salt or tap water?
Tap water would freeze faster but salt water would allow the waters freezing point to be lowered.
What will freeze in less than an hour salt or tap water?
Salt water freezes at a lower temp than fresh, meaning colder. It may freeze faster when chilled enough be cause the salt would disrupt the plateo of the water so it may freeze faster.
For water in glass plastic or styrofoam cups - which will freeze fastest?
Assuming they are the same or similar shape and volume, water in glass would freeze first, then plastic then foam. Foam allows transfer of heat out of water more slowly than plastic and the glass probably has the highest rate of heat radiation of the three.
If i put one spoon full of water in my cup would it freeze faster.?
it depends on what the heck you are talking about......
Would a marble or a plastic dice sink faster in water?
marble because it weight is more
Does tea or juice or fresh water or salt water freeze faster?
Fresh water is probably the likely candidate. If you add salt to a liquid, its freezing point lowers. Meaning, it would need a lower temperature for it to freeze.
What freezes faster sugar water or salt water or water?
Assuming you had equal amounts of each, the pure water would freeze first...Adding sugar or salt to water lowers its freezing point, meaning that more energy would be required to be removed from salt water and sugar water to freeze it
Which would freeze faster salt water or tap water with examples?
Tap water would freeze faster. That's the reason road crews apply salt to streets in the winter time. The salt water keeps the roads in a liquid state down to zero degrees Fahrenheit. Tap water is more like freezing rain. It freezes at 32 degrees Fahrenheit.
What would freeze faster soda with ice around it or with ice and water?
ice and water because the carbohydrates in the ice reflects with the soda's outer layer
